From: Elevated cerebrovascular resistance index is associated with cognitive dysfunction in the very-old
Mean CBF for young-old (black) and very-old (striped) groups within each significant cluster. Clusters shown resulted from voxelwise regression of MAP on CBF and survived the cluster threshold alpha-protection procedure (P < .05, volume >1,344 mm3). Coordinates (x, y, z) refer to maximum intensity values within each cluster (L = left, R = right, A = anterior, P = posterior, S = superior, I = inferior). CBF, cerebral blood flow; MAP, mean arterial pressure.
